traverses

for stationary

sources. To aid in the representative

measurement

of pollutant

emissions

and/or

total volumetric flow rate from a stationary

source,

a measurement

site Where the effluent

stream

is flowing

in a known direction

is selected,

and the cross-section

of the stack is divided

into a number

of equal areas. A traverse

point is then located

within each of these equal areas.

METHOD 2 Determination of stack gas velocity

and volumetric

flow rate. The average

gas velocity

in a stack is determined

from the gas density

and from measurement of the average

velocity

head with a Type S (Stausscheibe

or reverse

type) pitot tube.

METHOD

3 Gas analysis

for the determination

of dry molecular

weight. This method

is applicable

for determining

carbon

dioxide

and oxygen

concentrations and dry molecular

weight of a sample

from a gas stream of a fossil-fuel

combustion

process.

METHOD 4 Determination of moisture

content

in stack gases. A gas sample

is extracted

at a constant

rate from the source.

It is determined

either volumetrically or gravimetrically.

l•°mail: stacks@customstackaoalysis.com Page 3METHOD 26A TESTING

DESCRIPTION Samples were collected

following

EPA Method

26A. Three 60 minute

tests were performed. The equipment

used for testing consisted

of a Burrell Model B orsat analyzer

and a Custom Stack Analysis

Sampling

Apparatus

(EPA type). A type "S" pitot and.a

heated sampling probe was used with the sampling

train. All equipment

was calibrated

in the laboratory prior to the test. The sampling

nozzle and the pitot tubes were measured

on the day of the test. All calibrations

can be found in the appendix.

The gases are passed

through

a heated pyrex probe and a heated

glass four inch filter holder containing

Pallfiex

TX40H145 filter media.

The gases leaving

the filter were collected

in a series of six impingers

packed

in ice. The first, second

and third impinger

shall be of the Greensburg-Smith design

with a standard tip. The first two impingers

contained

100 ml of 0.1 N H2SO4.

The next impinger contained 100 ml of 0.1 N NaoH and the last impinger

was left empty. After passing

through the fourth impinger

the gases pass through

a "Drierite"

column

containing

about 500 grams of calcium sulfate

(CaSO4)

desicant

to remove

the remaining

water vapor. The dry gas then passed through

the hose portion

of the umbilical

cord to a Custom

Stack Analysis

Model #3000 stack sampling

module.

In the module

the gas was moved

through

the system

by a leakless air pump to a Rockwell

175-S dry test meter. The dry test meter exhausted

to a calibrated orifice to measure

the flow rate of the gases passing

throuqh

the sampling apparatus. A type "S" pitot tube was attached

to the sheath

of the heated

p•robe and nozzle. The orifice pressure

taps and the pitot tube were connected

to a Dwyer

dual 10 inch combination inclined-well

type manometer.

One half of the manometer

measured

the orifice differential pressure

(^H) and the other half measured

the flue gas velocity

head (^P). The temperature of the flue gas was measured

by a type "K" thermocouple

connected

to a Marlin Digital Temperature

Indicator.

The C02 and 02 levels were determined

using a Burrell "Industrial Model B orsat analyzer. Sample recovery

was performed

according

to USEPA

Method

26A section

6.2.
